Prev: init, mount: export the name_to_dev_t symbol
Next: page_mkwrite vs pte dirty race in fb_defio

This change only adds EXPORT_SYMBOL() for name_to_dev_t.

name_to_dev_t is in use outside of init/ but is not 'officially'
exported. It provides behavior that is useful for any code that may be
need to lookup a block device by major:minor or registered kernel name,
especially before there is a root filesystem.

Hopefully, this is the appropriate use of EXPORT_SYMBOL(). This
specific function seems to be a stable interface and is available
in include/linux/mount.h.
